just got my datalogger today and i love it. there is so much i can do with that tool, but i do not understand how to read all the outputs from the ECU yet. i have a basic understanding of what I am looking at, but want to know what the values correlate to such as specific voltages and readings. for example, not too sure how to read and interpret fuel trim percentages, o2 voltage trims, air hz readings, knock counts, etc. if anyone knows of some good websites where i can find out some information and read more indepth to gain a better understanding of how to read the outputs so i will be able to tune my car more efficiently, that would be a huge help. i will begin my search for information now, but thought i would post this ahead of time to help me if my search does not give me good results. thanks for the help in advance. by the way, if anyone is debating whether to get the datalogger or not...GET IT! this tool is priceless for tuning. you'd be surprised how out of sync your car was, even though you thought it was fast and running great.

There are numerous tuning related websites set up for different datalogger users. Most are yahoo groups so you could go to the yahoo groups main page and run a search. I know that there are TMO lists, 2G tuning lists, pocketlogger lists, etc.
